net_cfg.h

从Luminary官方网站下载的LM3S6000系列的UCos+Tcp/IP的源码, 经本人稍微修改后可直接在IAR6.2下编译通过,里面包括了LM3S6000系列的所有外设UART, PWn....

*               Timers are required for :
*
*               (a) ARP  cache entries
*               (b) IP   fragment reassembly
*               (c) ICMP low-network-resources monitor task
*               (d) TCP  state machine connections
*
*           (2) Configure NET_TMR_CFG_TASK_FREQ to schedule the execution frequency of the network timer
*               task -- how often NetTmr_TaskHandler() is scheduled to run per second as implemented in
*               NetOS_Tmr_Task().
*
*               (a) NET_TMR_CFG_TASK_FREQ  MUST NOT be configured as a floating-point frequency.

*                                NETWORK INTERFACE CARD CONFIGURATION
*
* Note(s) : (1) Configure NIC-specific parameters.
*
*               Consult the specific NIC's documentation to determine the NIC's required configuration
*               parameters; see also the specific NIC's source documentation in the following network
*               directory :
*
*                   \<Network Protocol Suite>\NIC\<if>\<nic>\
*
*                       where
*                               <Network Protocol Suite>        directory path for network protocol suite
*                               <nic>                           directory name for specific network interface card (NIC)
*
*           (2) Configure NET_NIC_CFG_INT_CTRL_EN to enable/disable any software to handle the presence
*               of a NIC interrupt controller.
*
*           (3) Configure NET_NIC_CFG_RD_WR_SEL   to select whether to implement the NIC's read/write
*               functionality with functions or macro's.
*
*               (a) When NET_NIC_RD_WR_SEL_FNCT,  NIC read/write functionality SHOULD be implemented
*                   as functions in the application-specific 'net_bsp.c' (or some other application-
*                   specific file) & MUST be prototyped in the NIC's 'net_nic.h'.
*
*               (b) When NET_NIC_RD_WR_SEL_MACRO, NIC read/write functionality SHOULD be implemented
*                   as macro's   in the application-specific 'net_bsp.h'.
*
*           (4) (a) Configure NET_NIC_CFG_TX_RDY_INIT_VAL to initialize the NIC-transmit-ready OS object with
*                   one of the following values :
*
*                   (1) 0, for NIC driver's that implement the NIC's transmit-ready status using a
*                              Transmit Empty    interrupt.
*
*                   (2) 1, for NIC driver's that implement the NIC's transmit-ready status using a
*                              Transmit Complete interrupt.
*
*               (b) This configuration currently applicable for single-transmit-packet-buffer NIC drivers ONLY.
*
*               See also 'net_os.c  NetOS_NIC_Init()  Note #1a'.
*
*           (5) Configure NET_NIC_CFG_TX_PKT_PREPARE_EN to enable/disable the early preparation of NIC
*               transmit packet(s) by the network interface :
*
*               (a) When ENABLED,  NIC transmit packet(s) are     prepared BEFORE waiting on the NIC's
*                   transmit ready signal.  This is useful for NICs that can simultaneously prepare
*                   transmit packet(s) while also transmitting previously-prepared packet(s).
*
*               (a) When DISABLED, NIC transmit packet(s) are NOT prepared BEFORE waiting on the NIC's
*                   transmit ready signal.
